Yep i looked at the D7000 when it first come out, but its just too small for me. I think we'll see a D400 DX, but I also reckon we may see a D500 or D600 FX, which will be the signal to tell us the line is finished as DX.

Cause when you think about it, what would you call a prosumer FX, they have used D70, D80, D90. The D100 started the DXXX line, D700 and D800 is used. Yeah I think D500 or D600 will be an FX model. Whats the bet they release a D400 DX, then a D600 FX, that will keep us all guessing for another 4 years on the D400 replacement!
